Wireless IP Cameras

I have a wireless IP camera network, that uses a Cisco System Power Injector, and a Cisco 2940 switch on a VLAN.  Presently none of my cameras are showing any video in my management software.  However if I go directly to each camera, and plug into them with a monitor they are displaying video, except the camera that has the Cisco System Power Injector at its location.  Can someone tell me how to test the Cisco System Power Injector to see if it is blocking the video at that access point?  Or perhaps give a few clear instructions on how to reset the device so that this issue is corrected?

I assume you are using the power injector to provide power to the wireless camera at that location? It's a fairly simple device that you put in-line between a non-PoE switch and a PoE capable end device. The injector is then connected with a power supply and provides power to that device through the unused pairs of the Ethernet cable. The pairs normally used for Ethernet (1+2,3+6) are unaffected and passed through the device back to the switch, so that once the end device is connect to the far end of the cable, it is provides power (from the injector) and network connectivity back to the switch (you may know all this already)...

So there is no way to 'reset' the injector, other than to disconnect power from it... it is possible that it is not working - does the IP camera connected to it power up when connected? Are you sure that camera is working? If you swap that camera with one of the others, does it work in the other camera's location and does the other camera not work at this camera's location?

It would help to know exactly what type of cameras these are... and if you cannot connect the management software to the cameras, that may be an issue with the VLAN settings of the computer running the management software...

Hello,

Yes, the first part of your response I was aware of, but I do appreciate you posting it just in case.  The cameras that is connected to the injector is the only one that looks like it is trying to show video.  It shows a completely black pane, and the other locations show red panes where there should be video.  The camera types are Bosch, and I have tried running the management software but it will not connect with the VLAN so that I can get to the cameras.  I was told that sometimes the injector can fail and this would cause the camera network to become unresponsive, so I unplugged the device and immediately plugged it back in, but this did not resolve the issue.  Is there a certain amount of time that need to wait before reconnecting the injector?

Thanks,

Is this vlan separate from your local LAN and is the management console in the same VLAN/subnet?

Disconnecting and reconnecting the injector SHOULD be restarting the device (the camera does require the injector for power, correct?). The power from the injector would be reapplied immediately to the Ethernet cable, so it's just how long it takes the camera to start up... if you don't see the camera starting up, then it may be the injector.

As I mentioned above, if the cameras are all the same, then swap two cameras and find out if the problem follows the camera or the locations and that will rule one thing out. Maybe the camera is faulty also? If you switch two, and this camera doesn't work in the other place, and the camera from the other place works here, then it's the camera. If this camera DOES work in the other place, and the other one does work here, then you know it's the injector, or the cable... I don't add in the port on the switch, since you are saying you are connecting a monitor directly to the camera, so presumably, the only two variables are the camera and power for it, right?

And then, yes, as Cheever000 mentioned, once the cameras are working, start dealing with the VLAN and making sure the management station in on the same VLAN as the cameras...

Hello Cheever000,

Yes, the VLAN is independent of the local LAN, and the management console are in the same subnet.

Hello BWaring,

I know that the other cameras work because I have a handheld CCTV tester, that allows me to plug the camera feed into the device to test the camera.  I am able to see the video the send the PTZ commands to the camera to move it.  The only one that seems to be having an issue is the camera located with the power injector.  Just to confirm are you saying to unplug the power injector again, and then plug it in again, which will reset it?

Thanks,

Does the camera have any other power connection? If the only power connection to that camera is the PoE from the injector, then yes, the camera should reset if you disconnect the power injector and reconnect it. But you did mention that you already did that... the camera has a light on it? When you disconnect the injector, does the light go out? Does it come back on when you reconnect it?

Again, I know that you know that the other cameras work - swapping a know good, working camera with the one you are having trouble with, will tell you if it is the camera or the connection. If you swap cameras and the known good, working camera does not work, then it's the cable/injector. If it DOES work, then it's the camera - and therefore the camera should NOT work when you connect it to where the good one came from... you've got to eliminate one variable at a time, if you can...

are you able to ping all cameras that are having the issue? Are you able to connect to the cameras managment interface via IP? If your network is one broadcast domain, what does the ARP table look like. I highly doubt that the injector is "blocking" video; you either have data traversing it or you don't.

Hello rfc1180,

I cannot ping any of the cameras, I can only connect to them directly.  I have not tried to troubleshoot the ARP as my thinking was since I could get video connecting directly, that there must be a point of origin that is blocking the connectivity with the switch.

Thanks,

If you can't ping any of them it but they work directly connected sounds more like good old networking ip addressing VLAN routing etc.

aj85 - I'm trying to get you to start at the beginning. You say the camera itself is not showing video when you are directly connected... reread my post and SWAP two cameras to find out if it is the camera or the cable... The others you see video when directly connected, this one you don't. It may be the camera... You obviously have a network issue as well, but if the cameras don't work, that doesn't matter...

Cheever000,

So where should I start with testing the VLAN?  Should I connect to the console of the switch and reset the IP's as it is using DHCP?

Thanks,
aj85

Cheever000Commented:
Ok to start is it in the same VLAN as the management console?  Then from there is it the same subnet.  If both of those are true, then start on the same switch in the same vlan.  If not make sure the VLANs are being routed to the one you are accessing from verifying IP addressing making sure gateways are good and so on.  If it is in a different VLAN start on the same switch make a port in the same VLAN and try connecting from there to the cameras.  If that doesn't work then you have something going wrong on the switch or VLAN.

BWaring,

Yes, you are correct, and I understand that I should be starting from the beginning.  So I connected the handheld testing equipment to that camera location as a bypass and it shows video when connected in the place of the existing camera.  So it is not the camera device that is failing, but something else that is causing the video not to show.

Thanks,
aj85

Cheever000,

Yes, it is on the same VLAN as the management console, however I did just replace the switch about 6 weeks ago and everything was working fine.  I will check the subnet and gateway.

Ok, up above you I thought you said that that camera was the only only one not showing video with the tester....

So IF the cameras are all "working" then, the next question is, how do they get IP addresses? Forget the switch and VLAN for a minute... Is it DHCP or static? If DHCP, can you assign static to the cameras and confirm that the management app can connect if directly patched to the camera (if the management station has a static IP also) from the cable that is currently connected to the switch? If so, that rules out the injector...

If yes, then, at that point, you need to make sure that switch has the camera ports and the management station port as untagged devices in the same VLAN and then you need to test connectivity, as Cheever000 has said... But make sure they work without the switch and VLAN first... Then you know its just a switch issue...

If the cameras are DHCP, then they should not be, best practice is static for IP cameras. Are you able to post the config of the switch?

Additionally, what is the network range of the IP cameras? Are there any routers in the network? Do you have a network map.

Hello All,

I have moved the camera and replaced it with a known good camera and I am having the same results, no incoming video.  I have also trying pinging the other camera with no success now, but again when I go to the cameras individually I am able to get video on my handheld.  It seems that there is an issue with my network although I have tried several things to troubleshoot this issue as well, with no results.  I have replaced the switch and connected to the console but do not see any issues with that device, as all lights are green.  Not sure where to go from here.

Thanks,

You get video on ALL cameras with the handheld now? Yes, if ALL the cameras work on the handheld, then the remaining issues are network... so on the network side, as has been mentioned, you are trying to configure the cameras on a VLAN... can you first test connecting to them without implementation of the VLAN? Just connect them to standard switch ports and test from there. You've got to get that working first; then you can move all those ports to the VLAN....

aj85Author Commented:
Hello,

Yes, that is correct all cameras work with the handheld.  I am not sure how to test them without the VLAN implementation as they are not on any outside network, and everything is controlled through the switch.  Are you saying disconnect the switch?

If you have it available, one easy way would be to connect those four cameras and the management station to a small switch and give the management station a statis IP. Then everything else is rule out.

aj85Author Commented:
Well that is what is how the entire system is setup, everything connects to the switch and then into the video management server.  At present I assigned a static IP to the server, but the switch is using DHCP and I am not receiving any video.

BWaringCommented:
If the cameras are all working, now, then you need to figure out if your VLAN settings are correct... in addition to not getting video on that one camera, you said the management station would not connect through the VLAN to the cameras. An easy way to check if it the VLAN settings on the switch is to REMOVE any VLAN settings from the 5 ports you are dealing with - the four cameras and the management server. If it STILL doesn't work, then it's not the VLAN. If you don't want to mess with the VLAN settings in the switch, put those 5 connections in a small, unmanaged switch, by themselves, and test pinging to each device. If that DOES work, then you know it's something on the other switch... most likely the VLAN settings... you need to make sure that all 5 ports are untagged in the same VLAN (not necessarily on the management server, if it needs to participate in any other VLAN)... if you rule out one thing at a time, eventually, you will find the problem. There are not too many pieces here to rule out...

aj85Author Commented:
Hello,

Okay I will take that path.  Just to confirm, I should save the switch settings to config_old.text for example, and clear the VLAN settings and have the switch return to the default of VLAN1 for example.  Then reconnect everything and see if the video begins to feed to the management server?

Thanks.

BWaringCommented:
What else is connected to the switch? Just the video equipment? That's only an 8-port switch, right, so if the video equipment are the only pieces that use anything on the switch, other than the default config, that may work....

aj85Author Commented:
Correct just the video equipment is connect, and  it is an 8 port switch device.

BWaringCommented:
If only the video equip is connected to this switch, then why the VLAN? Anyway, backup the config and reset...

Q - the IP cameras don't tag their frames with a VLAN id, do they?
Q - What about the management server?

Assuming the end devices don't tag their frames, than the switch defaulted should let you ping each camera from the management server. If you cannot ping them, and the devices don't tag their frames, then take a cross-over cable and connect the management workstation directly to a camera and confirm you can ping.... i you can't then there's got to be some setting on the cameras (I think not the workstation - that's just a Windows machine, right?) that is not set correctly.

Camera's work (tested from handheld), so now work on the basic network connectivity...

If you have a model/part number for the cameras, I'll see what info I can find beyond that...

Just a quick update, I was able to connect back to my switch, and I am now checking the config file for errors.  I should have something either tomorrow or Monday from my testing.

Hello,

Problem finally solved.  As it turns out there was a separate UPS device specifically used to power the router devices that was failing.  That caused the cameras to not get the signal.  Thank you all for your help, I am now moving on to trouble shooting other issues.......
